A landscape architect is planning an artificial waterfall in a city park. Water flowing at 0.536 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.40 m high and falls into a pool (see figure). (a) How far from the wall will the water land? m Will the space behind the waterfall be wide enough for a pedestrian walkway? (Assume the water must land 2 m from the wall to provide adequate space for a person to walk beneath the waterfall.) O Yes O No (b) To sell her plan to the city council, the architect wants to build a model to standard scale, one-fifteenth actual size. How fast should the water flow in the channel in the model? m/s

Half Life

The concept of Half Life has numerous practical applications some of them includes figuring out the effective drug dosage to finding out when a radioactive becomes safe to use. If you look for a career in Nuclear Physics you will need this concept.
